RAIL-CHAIR.

Specification of Letters Patent.

Application filed February 25, 1913.

Patented Dec. 2,1913. Serial No. 750,665.

To all whom it may concern:

Be it known that I, JAMES W. SHAKER, a citizen of the United States, residing at Mo- Keesport, in the county of Allegheny and State of Pennsylvania, have invented new and useful Improvements in RailGhairs, of which the following is a specification.

This invention relates to rail chairs, and has for an object to provide a chair of this character which can be readily attached and securely anchored to the rail ties without the provision of such clamping devices as spikes or the like.

Another object of the invention is to provide a chair which may be constructed from a single piece of sheet material, whereby its cost of production can be reduced to a minimum.

In the drawings, forming a portion of this specification and in which like numerals of reference indicate similar parts in the several views :Figure 1 is a perspective view of the chair. Fig. 2 is a longitudinal section therethroug Fig. 3 is a plan View of the blank from which the chair is constructed.

My improved chair is stamped preferably from a single piece of sheet metal and constructed to provide a horizontal base portion 1 and the embracing side flanges 2. These flanges are provided with inwardly extending portions 3 and the vertically extending portions 4, the latter being arranged at the sides of the web portions of the rail ends and the former being arranged in overlapping engagement with the base flanges of the rail ends. The vertical portions 4 are provided with suitable passages 5 through which suitable clamping devices may be extended and engaged with the rail ends, as is obvious.

The base portion 1 of the chair has its ends extended outwardly to form depending flanges 6 which extend downwardly against the outer sides of the rail ties, as shown in Fig. 1. These flanges are provided with Copies of this patent may be obtained for five cents each, by addressing the passages 7 which are arranged in line with passages 8 in the supporting ties 9 and in line with passages 10 in the depending brackets 11 which extend downwardly from the bottom of the chair. The alining passages described receive retaining bo-lts 12, the passages 10 in the brackets 11 being suitably threaded to correspond with the threads of the bolts. The flanges 6 are substantially of dovetail configuration and their ends are bent inwardly to form anchoring spurs 13 which are adapted to be driven into the rail supporting ties. Prior to placing the chair upon companion ties, the flanges 6 may be bent up so as to permit them to readily adapt themselves to the proper positions relatively of the ties. Afterward the flanges may be bent into proper vertical positions so that the spurs will enter the sides of the ties, as shown.

F ro-m the construction described it will be seen that an extremely simple and inexpensive chair is provided which may be readily applied to the well known forms of supporting ties and to the rail. The construction is such that on adjusting the bolts 12 so as to secure the chair to the ties the tendency of the bolts in such adjustment will be to draw the flanges 6 toward each other, resulting in the spurs 13 of the flanges entering the ties.

I claim:

A rail chair comprising a member having a base portion, depending end flanges on the base portion, brackets extending downwardly from the base portion, and fastening devices extending through the flanges and engaged in the bracket and adapted to be extended through the rail supporting ties.

In testimony. whereof I aflix my signature in presence of two witnesses.
